Days P5716 month

Meaning of the questions: Enter a year and a month to determine the year for a few days this month to consider a leap year

Note: There are 31 days Otsuki 135781012 Satsuki 30 days with a 469,102-average special February 28 days, 29 days leap year

          Analyzing conditions are leap year is a leap year divisible by 400, or divisible by 4, can not be divisible 100

        Function to define a month, then use the switch statement, can play a large monthly output is still Satsuki

       Then define a function of determining whether a leap year

     Finally, the output function
